The SMC EX250 valve terminal has an IP-Link interface and can therefore be integrated into the Fieldbus Box system. The direct combination of fieldbus and I/O variety with pneumatics offers a large number of application options. Like an Extension Box, the valve terminal is connected to the Coupler Box via the IP-Link bus; the distance may be up to 15 m. The Coupler Box is the head station with the integrated fieldbus connection, to which up to 120 extension modules can be connected. No special configuration is required in the system integration, because the Coupler Box automatically recognises the modules.
